Region 11834 [N13W65] displayed no major changes and was mostly quiet.
Region 11835 [S10W52] developed slowly with new flux emerging in the
south.
Region 11836 [N11W23] was mostly quiet and stable.
Region 11837 [S17W33] was mostly quiet with the main penumbra increasing
in size.

Spotted regions not numbered by SWPC:
New region
S2655 [N03E52] emerged with a penumbra spot.
New region
S2656 [S07E10] emerged with a penumbra spot.

Long distance low and medium frequency (below 2 MHz) propagation along paths
north of due west over high and upper middle latitudes is poor to fair. Propagation on
long distance northeast-southwest paths is poor to fair.

The geomagnetic field is expected to be quiet to unsettled on
September 4 due to effects from CH583 and quiet on September 5-6.

Coronal holes (1)

Coronal mass ejection (2)

M and X class flares (3)

1) Effects from a coronal hole could reach Earth within the
next 5 days. When the high speed stream has arrived the color changes to
green.
2) Effects from a CME are likely to be observed at Earth within 96 hours.
3) There is a possibility of either M or X class flares within the next 48
hours.

When available the active region map has a coronal hole polarity overlay
where red (pink) is negative and blue is positive.

Data for all numbered solar regions according to the Solar Region Summary
provided by NOAA/SWPC. Comments are my own, as is the STAR spot count (spots
observed at or inside a few hours before midnight) and data for regions not
numbered by SWPC or where SWPC has observed no spots. SWPC active region
numbers in the table below and in the active region map above are the historic
SWPC/USAF numbers.

1) Running average based on the daily 20:00 UTC observed solar flux value at
2800 MHz.
2A) Current impact on the monthly sunspot number based on the Boulder
(NOAA/SWPC) sunspot number (accumulated daily sunspots / month days). The
official SIDC international sunspot number is typically 30-50% lower. 2B)
Boulder SN current month
average to date. 2C) STAR SDO 1K Wolf number 30 day average.
3) Running average based on the quicklook and definitive Potsdam WDC ap indices.
Values in red are based on the definitive
international Potsdam
WDC
ap indices.
